Final Warning Before Termination: What Employers Legally Must Do

Upeka Bee

As a small business owner, firing someone can feel like tiptoeing through a legal maze. You’ve likely heard about ‘final warnings’ and ‘probation periods.’ But what’s required by law and what’s just a smart business practice?

Let’s unpack the facts. Knowing how to fire someone legally and professionally helps you avoid lawsuits, protect your reputation, and maintain fairness across your team.

The ‘At-Will’ Foundation: Where You Start

In nearly every U.S. state (except Montana), employment is ‘at-will.’ This means you can fire an employee at any time, for any reason or without reason (as long as it's not illegal).

Still, this doesn’t give you a blank check. You can’t fire someone based on race, gender, religion, age, disability, or other protected characteristics. Nor can you fire someone for engaging in protected activities, such as reporting harassment or taking FMLA leave.

Even in an at-will state, having a clear, documented, and non-discriminatory reason is your safest bet. That’s where final warnings and probation periods matter.

Are Final Warnings Required by Law?

No federal or state law mandates a ‘final warning’ before terminating an at-will employee. But skipping them altogether isn’t wise.

Here’s why documented warnings matter when deciding how to professionally fire someone:

  • Legal Protection: If you're ever accused of wrongful termination, a documented trail of underperformance helps prove your decision was lawful.

  • Employee Awareness: Clear feedback provides employees with the opportunity to course-correct and make adjustments.

  • Fairness and Consistency: A defined warning process protects against bias and builds trust.

  • Unemployment Disputes: If you challenge an unemployment claim, written records of misconduct or poor performance help your case.

If your employee handbook outlines a progressive disciplinary process, you’re expected to follow it. Courts may treat it as a binding policy.

Understanding Probation Periods: What They Really Mean

Think of probationary periods as trial runs for new hires. Most last 30, 60, or 90 days, giving you time to assess fit, performance, and attitude.

What you can do during probation:

  • Fire without extensive warnings: Since at-will rules still apply, you can terminate someone during probation if they’re clearly not working out.

  • Delay some benefits: Some employers start health insurance or PTO only after the probation period ends.

What you can’t do:

  • Ignore anti-discrimination laws: You can’t fire someone for protected reasons, such as pregnancy, age, and disability, even during probation.

  • Skip wage and hour laws: Minimum wage, overtime, and workplace safety rules still apply.

  • Break employment contracts: If you’ve promised ‘for cause’ termination or a notice period in writing, you must honor it even during probation.

How to Professionally Fire Someone (The Right Way)

Whether you're firing someone for stealing or for performance issues, here’s how to fire someone legally and properly:

  1. Document Everything: Track attendance, performance, feedback, and policy violations.

  2. Be Consistent: Apply your rules evenly across all employees. Inconsistency can lead to discrimination claims.

  3. Understand State Laws: Federal law sets the baseline, but your state may have extra rules (e.g., final paycheck deadlines or mini-WARN acts).

  4. State a Clear Reason: Say exactly why you’re letting someone go, for instance, ’performance issues,’ ‘policy violation,’ etc. Avoid vagueness.

  5. Prep for the Meeting: Have your paperwork ready—final check, COBRA details, benefits info.

  6. Don’t Fire Alone: Have a second person (like an HR rep) witness the meeting.

  7. Offer Severance (If Appropriate): Not required, but severance can smooth things over and reduce legal risk.

FAQs

How do you fire someone for stealing?

Gather evidence, document the misconduct, and conduct a fair investigation. Follow your internal policy, offer the employee a chance to respond if required, and comply with state laws for termination.

Is it better to fire someone on a Monday or a Friday?

Aim for early in the week, such as Monday or Tuesday. It gives employees time to access support resources during business hours, rather than having to wait until the weekend.

Can you fire someone without cause in an at-will state?

Yes—but never for a discriminatory or retaliatory reason. Even without a legal requirement, having clear, documented reasons helps protect you.

Do you need a performance improvement plan (PIP) to fire someone?

Not legally, but it’s best practice. A PIP outlines performance issues, goals, and timelines. It shows you gave the employee a fair shot.

How to professionally fire someone for poor performance?

Use a structured approach. Document performance gaps, communicate expectations clearly, and offer support. When necessary, conduct a respectful and private termination, ensuring all required paperwork is in hand.
